Xiaomi Yi 1600x1200 recording

[Magic_MTN]

Figured I would create a new thread.
I am using a Yi action camera
model z26l currently on firmware 1.4.8

My intention is to capture images of biking and skiing at 1600x1200 resolution and using that picture to fill a frame of 1280x720 for final result.

capturing at a higher resolution allows me to reposition the frame based on what is captured, or take advantage of image stabilization techniques using the extra pixels.
I used am using the yimax pro scripts found in this thread for my camera and attached to this thread:
https://www.goprawn.com/forum/main-f...-z26l-fw-1-4-8

The script tells the camera to record at [email protected] I have it set to 35mbps.
the footage from my morning commute on a cloudy day looks decent. I applied a warp stabilization effect on this clip to make it a little smoother.
the footage from my evening commute has a lot of grain. no stabilization effect on this footage.

Anyone have any tips for less sensor noise in low light.
I was expecting some diffrent results.

Maybe something with the script or default camera settings..
I have tried playing with auto low light as well as spot and average metering.

Thanks

Going to keep updating the thread:
upgraded firmware to 1.5.6

tweaked the script a little as I noticed i was not recording at full 35mbps
raised the denoise value to 2048

will post results along with new script tomorrow.

I'd be very interested when you get this sorted. I'm shooting VR with 7 Cameras. I need the 1600x1200 resolution.

[benniknop]

Seems that the bitrate is only 15.17 Mbit/s on mine, the resolution is correct. Is that the same with your's?

[Magic_MTN]

what model is your camera? what firmware are you on?

[Magic_MTN]

Here is the script i have been using most regularly.
I tested this weekend on some ski footage and the results look good in daytime.

The most extreme conditions I will record in is my evening bike commute.
For this I have had mixed results but the script below is what I have landed on and stuck with so far.

the few changes I made were:

Noise reduction:
I set this value to 2048 but UI know it can go higher than that but i feel this is a ok balance for now.

Raw and jpeg:
the raw never worked for me so i commented this out

Scene mode set to 12 not 9
this seems to be a little better in low light

here are some results

[benniknop]

Z26L with 1.5.6 firmware. You're other 2K one works at full bit rate. The 1200p 60f didn't go higher than 15 Mbit/s

[benniknop]

I just tried the last script you sent and this is what I got.

[benniknop]

2304x1296 at 15 Mbit/s

[benniknop]

From the below script I get 40.29 Mbit/s at 2304x1296

Do I have to do anything on the app??

[Magic_MTN]

I don't think you need to do anything on the app.
